Remodeling of cholesterol metabolism in melanoma progression regulates nuclear membrane mechanics.

This study shows that cholesterol metabolism remodeling in melanoma progression alters nuclear membrane mechanics, increasing tension and vulnerability to rupture during cellular confinement.

Deep Vein Thrombosis-primed neutrophils reshape the brain microenvironment to promote brain metastasis

This study shows that deep vein thrombosis primes neutrophils to promote brain metastasis in triple-negative breast cancer by enhancing their recruitment and NET formation.

APOE4 and INPP5D converge on membrane mechanics to regulate endocytosis in human astrocytes

This study shows APOE4 impairs endocytosis in astrocytes by altering membrane mechanics, and INPP5D restores this process by promoting clathrin curvature and maturation.

BLOC1S1 regulates autolysosomal and exosomal dynamics during CD4⁺ T cell differentiation

This study shows BLOC1S1 deficiency in CD4+ T cells leads to altered lysosomal and exosomal dynamics, enhancing Th2 immune responses through exosome-mediated cytokine export.

OBESITY-INDUCED ENDOTHELIAL FENESTRATION AND CAPILLARY LEAKAGE CONTRIBUTE TO INCREASED PAIN SENSATION

The paper shows obesity causes capillary leakage in skin, leading to NGF production and pain hypersensitivity, suggesting capillary permeability as a therapeutic target.

ISG15 orchestrates dynamic crosstalk between mitochondrial fat oxidation and type 1 interferon in myeloid cells

This paper identifies a biphasic regulatory loop where type 1 interferon initially enhances mitochondrial fatty acid oxidation (FAO) to amplify its own production, but excessive IFN signaling induces ISG15-mediated inhibition of FAO, creating a negative feedback loop to control inflammation.

Triglyceride metabolism controls inflammation and APOE4-associated disease states in microglia

This study shows that triglyceride metabolism is essential for microglial activation and disease states in APOE4 microglia, with implications for modulating immune responses.

Mitochondrial DNA removal is essential for sperm development and activity

This study shows that mitochondrial DNA removal is essential for sperm development and activity, revealing a novel exonuclease, ExoA, required for mtDNA elimination and preventing nuclear-mito imbalance.

BLOC1S1 control of vacuolar organelle fidelity modulates TH2 cell immunity and allergy susceptibility.

This study shows that BLOC1S1 depletion disrupts mitochondrial integrity, leading to TH2 cell immunity and allergy susceptibility via STING-NF-κB signaling.

Developmentally-orchestrated mitochondrial processes prime the selective inheritance against harmful mitochondrial DNA mutations

The paper investigates mtDNA selective inheritance in Drosophila, showing that developmentally-orchestrated mitochondrial processes like fission and transcription enable purifying selection against harmful mutations.
